(FILED UNDER THE ACT OF MARCH 3, 1883, 22 STAT. In, 625.)

To all whom it may concern.

Be it known that I, ALEXANDER M. BEL- LONY, captain, Corps of Engineers,United States Army, a citizen of the United States, stationed atWashington, D.. (1., have invented an Improvement in Wheel Blocking andJacking Devices, of which the following is a specification.

The invention 'described herein may'be used by the Government, or any ofits officers or employes in prosecution of work for the Government, orby any other person in the United States, without payment-of any royaltythereon.

The general object of my invention is to provide a novel wheel blockingand jacking device which shall be simple in construction, efficient inoperation, and susceptible of application and removal with greatcelerity.

While my device may beused to advantage in connection with wheeledvehicles or machines generally, it is especially valuable forapplication to pile-driving machines, because it eliminates thenecessity of taking off the wheels of the pile-driving machine when thelatter is in operation driving piles. By the use of my invention inconnection with pile-driving machines there is no loss of time inchanging rollers, or in building a roller bed for moving the machine,and the time consumed in looking and releasing the wheels by mymechanism is reduced to a minimum. I

The invention, broadly considered, resides in pairs of complementalwheel' blocking members, and in means for tightening and holding saidmembers against the wheels of the machine.

The invention also resides in the combination, with the structure notedin the preceding paragraph, of screw jacks carried by the wheel blockingmembers, or a portion thereof, for forcibly bearing against the undersurface of the frame of the pile-driving machine, or the like, andforcing the wheel blocks carrying said jacks forcibly against theground, thus frictionally holding the wheel blocks and wheels againstmovement.

'WVhere the pile-driving machine is mounted wheel-blocks withwheel-bearing surfaces, 7

curved in conformity with the contour of the wheels to which said blocksare-applied, said refinements going to make up the ultimate perfectionof the entiremechanism.

The invention is graphically illustrated in the appended drawings, theseveral views of which may be briefly described as follows:

Figure 1 is a side elevation of a pile-driving machine (in skeletonoutline), showing the application of my'wheel blocking and jackingmechanism thereto; Fig. 2 is a topplan view, partly broken away, of saidmechanism;

Fig.3 is a vertical sectional View along the line 38, Fig. 2; and

Fig. 4 is a detail View in perspective, partly in section, of one of thewheel, blocks. Referring now. in detail to the drawings:

The wheel-blocking members preferably comprise blocks 1, desirably ofgeneral rec tangular shape, as shown. A pair of such blocks may beadvantageously used for each wheel A'of the object carrying such wheels,in this instance a pile-driving machine.

Advantageously, each of these blocks may be recessed, as shown, forinstance, very clearly in Fig. 4%, to provide a downwardly inclinedlongitudinallv curved bearing-face bounded at the sides by verticalwalls. The curvature of said hearing faces corresponds to the contour ofthe peripheral portions of the wheel A.

Said recesses maybe appropriately lined with metal or like wearresisting material, as shown at 2', said liner being, if desired,provided with flanges 3, through which fastening means 4 may pass'tosecure'the liner to the block.

Reenforcing means for each block may be provided, in this instance metalstraps or hands 5 encircling the blocks and secured theretobyappropriate means 6.

Extending transversely of the block from side to side thereof and oneach side of said metal recesses are guide holes 77, which are alsoadvantageously metal lined, as shown at 8. The holes 7 of one of theblocks forming each pair may be of greater diameter for a portion oftheir length, as shown in Fig. 2 in respectto the block at the left handthereof. The metal liner of the holes may be provided with flanges 9bent a ainst the sides of said blocks and secured thereto by suitablefastening means.

Certain or all of said blocks may be procros's-sectionally vided with anaperture 10 therethrough 6X- tending at right angles to the guide holes7 7. A portion of said aperture 10 is of larger diameter, forming anannular shoulder 11 in the wall of said aperture intermediate the endsof the latter.

Projecting into said aperture 10 is a screw-jack barrel 12 resting atits bottom upon said shoulder 11, and provided with a threaded bore, asshown, and with a head 13 which is secured by suitable fastening means 11 to the block 1.

Threaded into the bore of said screwjack barrel is a screw-jack 15carrying a head 16 of appropriate shape to engage the frame of themachine. In this instance the head is shown provided with a diametricrib 16 on its upper surface, adapted to engage the frame channel bar Bbetween the depending flanges thereof.

Insertible through the holes 7 of one block of each pair are bolts 17having atone end a hook 1'8 and having its other end threaded, on whichmay be screwed a nut 19, a washer 20 being interposed between saidnutand the block 1.

The hook 18 of the bolt 17 engages the eye 21 at one end of a link 22provided at its other end with a hook 23 engageable with the eye 2% of ascrew bolt 25 projecting through the hole 7 of the other block andcarrying a collar 26 (see Fig. 2) adapted to be passed into the sectionof the hole ha ving the larger diameter. The nut of the screw boltopposite the eye 24 is threaded, on which may be screwed a nut 27. Saidnut is removably carried by a handle or lever 28, having, at one end, ayoke 29, into which may be threaded screws 30, whereby the lever issecured to said nut.

In operation, one of said blocks is placed at each side of a wheel ofthe machine and the hooks 22 are thereupon coupled up with the screwbolts 25, and the levers 28 are manipulated to tighten up the nuts 27 onthe screw bolts 25, thereby tightening the blocks 11 against the wheel.The screwjack 15. is thereupon rotated until the head thereof firmlybears'against the frame of the machine, thus forcing the block carryingsaid screw-jack with considerable pressure against the ground, therebytending to prevent the blocks being dragged by the.

pile driving machine, in the operation thereof.

The many advantages of my invention will be apparent, and will appealespecially to those skilled in the art to which the invention pertains.The mechanism comprises but few parts, which are not likely to get outof order; the device is capable of being applied with great rapidity;and the mecha nism, in operation, is exceedingly efficacious for thepurpose intended.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:

l. A combined wheel blocking and jacking mechanism, comprisingcomplemental, slidable wheel engaging members disposable one on eachside of a wheel, means for sliding said members toward each other andagainst the wheel, including a detachable coupling between the members,a screw jack barrel carried by one of said members and having a threaded'bore and a screw jack threaded in said bore.

2. A combined wheel blocking and jacking mechanism, comprisingcomplemental wheel engaging members disposable one on each side of awheel, means for sliding said members toward each other and against thewheel, including a detachable coupling between the members, a jackbarrel carried by one of said members and a jack operable in saidbarrel.

3. A combined wheel blocking and jacking mechanism, comprisingcomplemental wheel engaging members disposable one on each side of awheel, meansfor sliding the members toward each other and against thewheel, a ack barrel carried by one of said members and a jack operablein said barrel.
